Moynihan
family name
Moynihan is a surname of Irish origin.
Recorded in several spellings forms including Moynihan, Monahan, Monaghan, Monaham, Minihane, Minihan, and probably others, this is an Irish surname of great antiquity. It originates from the Irish language Ó Muimhneacháin, which literally translates as "male descendant of the Munsterman" (or "Ní Mhuimhneacháin" for female descendant and "Uí Mhuimhneacháin" for wife of the Munsterman). The surname is most popular in Counties Cork and Kerry, which form part of the province of Munster. The modern spellings are usually Moynihan and Monaghan, the spelling in the 16th century being generally recorded as Minighane, and regarded as the principal surname of West Cork. Michael and Mortimer Moynihan were famous rebels in the late 16th century, and hailed from Skibbereen. Several of the name were famine immigrants into New York City, who embarked from Liverpool on the ship Hampden bound for that port on December 8, 1846. The first recorded spelling of the family name is shown to be that of Teag Ó Muimhneacháin, dated 1659, in the Barony of Tulla, during the reign of Richard Cromwell, Lord Protector, between 1658 and 1660. Throughout the centuries, surnames in every country have continued to "develop" often leading to astonishing variants of the original spelling.

Overview language is designed for orientation and should not be treated as a substitute for the evidence cited beneath it. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
